■purpose
In winter, as the ambient temperature decreases, the heating efficiency of the central air conditioning system also decreases. When the difference between the ambient temperature and the standard operating temperature is large (the standard operating outdoor temperature is 7 ℃) and the temperature is below 4 ℃, the central air conditioning system will not be able to provide the required temperature for the room. In order to supplement the insufficient heat, it is necessary to add auxiliary heaters on top of the existing heating equipment.
■advantage
High thermal efficiency, high safety, reasonable structure, strong corrosion resistance, and long service life.
